This calculator is designed to find the external surface area of a pipe in square feet (ft²). This calculation is essential for estimating the amount of paint, coating, or insulation material needed for a piping project. Simply enter the pipe's outer diameter and its total length to get the result.
The calculation uses the standard formula for the lateral surface area of a cylinder:
Area = π × D × L
Where:
- Area is the total surface area in square feet (ft²).
- π is the constant Pi (≈ 3.14159).
- D is the outer diameter of the pipe in feet (the calculator converts the provided inch value).
- L is the length of the pipe in feet.
Example Calculation:
For a pipe with an outer diameter of 2 inches and a length of 10 feet:
- Convert diameter to feet: D = 2 in / 12 = 0.167 ft
- Calculate the area: Area = π × 0.167 ft × 10 ft = 5.24 ft²
The total surface area is 5.24 ft².
